To all whom it may concern:

Be it known that I, SWAN J. Venus-rpm, a citizen of the United States, and a resident of Chicago, in the ct'mnt-y of Cook and State of Illinois, have invented certain new and useful Improvements in Continuous Pre of which the following is a full, clear, an exact specification.

My invent ion is concerned with cont-1nnulls presses of the type in which the material to be operated upon is fed between two slightly-com'erging perforated-belts, so us to allow the water, etc, to pass throu h the belts as it is squeezed from the material as its bulk is lessened by the convergence chine with the right-hand side thereof in ccntml vertical section; F 2 is an end elevation, with the right-han portion thereof in vertical section through one of the upper and lower drums, and with the belts (unified in order to ex se the drums; F i is :1 plan view in section on the line A. 1 of Fig. l Fig. l is a detail of a part of the exterior of one of the belts: Fi 5 is a view of the same in section on the inc BB of Fig. 4; Figs. 6, 7 and 8 (Sheet 1) are side,

the machincyus sceu 'ln "iii; 2 are p open, and have at the 'oti end and Ian views, respectively, of the blocks used in adjusting the hearings of one of the lower drums, and 9 and 10 are end and side views, respectively, of the acking rings used in connection with the ower drums.

Int-he preferred embodiment of'm invention, the front. and rear of the mac inc are formed of the two frame news 11 and 12, which may be cast into ra ly or'built up'in any desired manner'. heir principal function being to furnish supports for thera- -rious bearings with which the moving arts of the machine are equip d. The an s ofreferom t B'ICOD'.

[ net-ring base stri s 13.

The intermediate bearing rmg 42 is vlded with a-snnllur annular chunne 4B1 ou its'interior, and an oiling;a rture44 in The frame pieces are connected an spaced apart at suitable intervals by the tie rods 14. The power is applied to the machine. to drive it by means of the horizontal worm shaft 15, which is journulcd in suitable bearings 16 on the end plate 11, and this shaft is provided with the pair of oppositely pitched worms 17, which mesh with the worm wheels 18 and 19 secured on the outer ends of the shafts 20 and 21. which are journaled in the bearings .22 and 23 in the frame 11, and 24 and 25 in the frame 12. At their other ends, outside of the bearings 24 and 25, the shafts are provided with the sprocket wheels 26 and 27, which, through the sprocket chains 28, drive the sprocket wheels 29 secured on the correspondmg ends of the shafts 30 and 31, which are journalcd in the bearings 32 supported from the end late 11, and 33 supported from the end p ate 12. As best seen in Figs. 1 and 2, these bearin s 32 and 33 are adjustable, their lateral atliustment being secured by means of the set screws 34 provided with the lock nuts 35, which screws are threadedthrough apertures in the 111 s 36. These baa-rings are supported vertically and their lateral movement permitted b means of the bolt 32', the upper end of whi 1 is screwed into the bottom of the bearing block, while its semispherical lower end is mounted in a correspondingly shaped recess in the bearing lug 3S promoting from the frame pieces. This simple adjustment enables me to more the two shafts 30 and 31 to and from each other as may be newssary in seem-in the proper distance between the upper en s of the effective portions of the two belts to be described.

The bearings22 and 24, and 23 and 25, for

external= annulus 59 for the bearings 22 and 24, while in the bearings 23 and 25, the cor responding part has an elon ted rectangular shape, as indicated by t e dotted'lines in Fip. 1, in order to rovide for the-horizonta adjustment off a shaft 21. The 'nn- .nulus 39 preferably has the interior, shallow annular channel 40, and o ning into this channel at the top is the oi tug aperture 41.

.linewith the aperture 41. einnorinostl annulus 45, in which the shaft turns, has

the longitudinal channel 46 on the interior of the bottom of the sleeve, and this channel 46 is connected by the aperture 47 with the channel 43. lhe bearing sleeves are held from turning in any desired manner, and it will be evident that if a quantity of oil is poured into the aperture 41, it will fill the channel 43, and some of it will rise through the aperture 47 into the channel 46, and this portion of the oil serves to lubricate the bearing. This construction will preserve the desired degree of lubrication for a long )eriod without any attention whatever.

he construction of the lower bearings 24 and .25 is similar to the bearings 22 and 23. except that the bearing members corresponding to 32) are of an elongated, rectangular shape to permit of the horizontal adjustment, and the intermediate members 42 have their exterior square so as to slide in the elongated rectangular aperture.

In order to furnish a convenient method of adjusting the position of the shaft '21 4 without any difliculty in getting into the bearings owing to the the adjusting blocks 48, which, as will be seen from Figs. of metal with resence of the wheels 19 and 27, I provi e a plurahtv of 6, T and 8, are merely strips the recesses 49 thereto 11] order to permit a tool to be inserted therein to facilitate their withdrawal. these blocks between the intermediate hearing member and the rear of the exterior bearing member, the position of the shaft 21 can be accurately regulated, and it needs By using no blocks on the inner side, owing to the g ressure of the material operated on holding 1 frame, as seen in Fig. 1. It will be understood that the shafts 30 it back in place.

and 31 are provided with the drums 50 and 51, which are secured to and rotate with the 1 shafts, and surfaca in t referably have their exterior l e form of smooth cylinders The shafts 20 and 21 carry the perforated perforated, endless belts, the details of which are to be described, are passed around the drums 50 and 52, and 51 and 53, respectively, and the shafts 20 and 21 are setcloser to ther than the shafts 30 and 31, so that t e belts will converge, so that. any material thrown between them as they pass over the cylinders 30 and 31 will be squeezed very-strongly as the space between the belts diminishes as they ass to the drums 52 and 53. In order to 101d the adjacent portions of the belts rigidly between the drums 50 and 52, and 51 and 53, and also to adjust the distance between them at this point, I provide the pair of rollers 54 and 55, which are journaled in four similar bearings 56, which are adjustably mounted they are made up of sections. each of which consists of a plate 58. which is curved to correspond with the curve of the periphery of the drums Til and 32%. where cylindrical drums are used. and which might be flat. if these drums were polygonal in cross section and had a number of flat surfaces cO1t't spondine' in size to the belt section These plates 58 are provided with the alternate cars 59, which intcrmesh so that the hinge rod 60 may connect the sections to form a continuous, substantially flexible belt. The. belt is provided with the perforations (31. which are of a considerable size, and as numerous as compatible with the desired strength of the sections. and I find that the best results are secured by making these perforations larger on the interior of the belt than the exterior, and they are preferably of a truncated conical shape, or flaring, as

shown. To prevent the material being op- ,u.

erated on passing, with the moisture through the large perforations 61, I cover the ex terior of each section with a sheet of finely perforated metal 62. which is referably composed of brass. and is secur in place by the strips (53 at the top and bottom, which strips are preferably detachablv secured in place by the screws til threaded into the plates 58. so that the screen can be readily removed for repairs. In order to enable me to conveniently remove any section of the belt endwise through the framework of the machine, I provide the apertures in the The drums 5-2 and 53 are designed to re, ceive the moisture from the lower part of the belt, and in order to pass the moisture into the interior of these drums so as to prevent its falling oil from the belts and dropping down with the material into the conveyer trough 66. I provide the drums with the perforations 6?. and in order to prevent later. It will be understood that a pair of the moisture which tends to run through these perforations when they are in the horizonta position from running out again as they assume a vertical position, I preferably extend the perforations, as it were, by securing the tube 68 on the interior of the driun. and it will be apparent that by employing these tubes, the moisture will have no chance to run out until enou h has accumulated in the bottom of the drums to extend above the tops of the tubes, and I r0 ride means for draining the drums, as est seen in Fig. 2, where it will be seen that the drums have the apertures 69 which register with sullicient frequency with the apertures 70 formed in the end piece 19., and provided with a spout 71', which is internally threaded, as seen at 72, so that it may be connected Stl perforations: GT in these grooves.

with a waste pipe provided to carry away the moisture.

resulb' with this arrangement. it is advisable to make the bearings between the ends of In order to secure the best 15.

the drums 52 and 54 water tight with the interior of the frame pieces 11 and 12. and.

for this purpose. I employ the metallic packing rings 73. which are mounted in the grooves 74 in the ends of the drums. and have the pins T to prevent their turning.

and the springs to pre-zthe rings against the frame pieces. the pin. and springs. of course. being located in suitable recesses extending: inward from the grooves T-l. .idditional tween t :e cnd of the drums and the packing rings 4.3. but this is not so important.

While the pcrt'orationa- 6} alone might be depended upon to carr v away the moisture front the perforations G1. I preferably insure the moisture being carried away by providing the longitudinal grooves TS extemliug lengthwise of the drums and locating the' By the arrangement shown. it will be seen that the bulk of the water squeezed out of the material will paw; into the interior of the drums 52 and .33. and be discharged through the waste pipes connected with the spouts 71. How

' ever. totalic care of whatever moisturemight escape from the drums and whatever material might drop therefrom. I provide the sheetinetal troughs Til. which extend across the machine between the frame pieces and benching 7? may be interposed beneath the drums. and the shorter, inner. inj clined portions of which are connected with the upper edges of the conveyor trough l 66. while the other portion 81 extends up higher and to the outer edge of the tnachine. so that any material accumulating in thc troughscan he raked out. In order to permit the moisture to escape from the troughs and not. overflow into the conveyer trougi-i G6. I provide the perforations in the troughs just below the level of the upper edges of the side; 80 and the conveyor trough 66. Then. as the material accumulates in the trough. it can be scraped u and thrown back into the top of the machine to l'O-SQHCQZB this portion of the material. The conveyer trough 66. which receivee the squeezed material. is provided with some conveyingapparatus, suclh for instance. as the screw S3 secured on the shaft 84. and this shaft 84 is journaled at. one end in a suitable bearing in the frame piece 12, and is provided at this end with the miter gear pinion 8!. which meshes with a miter gear pinion Sf: secured on the horizontal shaft 87 journaled in the l'ieariugs 88. 89 and 0 secured to the frame piece 12. The outer end of the shaft 87 is provided with the sprocket wheel 91. which is driven through the sprocket chain 02. indicated in Fi 2,1131 the sprocket wheel 93. indicated in rotted lines in l 'igwi. secured on the end of worm shaft Iiv thew driving connections of the convcyer shafl with the drums. it will be cvitlcnl that the conve ver is rotated in synt'ltltHlir IH and at the proper rate of speed relative to the tll'ltllh so that the material is carried nli' as fast as it is tfllllpl'fifi 'l'tl.
